Contrary to what one might think, sugar promotes sleepiness and not hyperactivity. There may be a good reason to sleep after a high-sugar meal. That is the conclusion of a new study published by neuroscientists at ESPCI ParisTech in collaboration with the Lyon Neuroscience Research Center. This study demonstrates that glucose promotes sleep by activating the neurons responsible for sleep onset and maintenance. These neurons integrate energetic signals such as ambient glucose directly to regulate vigilance states accordingly. This work was published in the Journal of Neuroscience.
What does happen when one blows in a soda can? An almost pure tone is generated, a signature that it resonantly interacts with audible sound. At a different scale, a similar phenomenon occurs when a light wave interacts with a material. The interaction depends on two criteria: the chemical composition of the material, and its atomic structure.
Researchers from the Institut Langevin (ESPCI ParisTech, CNRS) have developed an original experiment based on honeycomb arrangements of soda cans to create an acoustic superlens. Their work was published in the renowned Nature journal on september 4th, paving the way for new research in the field of composite materials.
50%. This is the percentage of female students present in the ESPCI’s 134th promotion of 2015. For the first time in the school’s history, the traditional male tendency of engineer schools is overturned.
